The present invention relates to a method for loading textile material particularl material containing silk in the form, of anks or runs.

The invention includes the provision of a single centrifuge common to a number Aof su ply tanks and Huid circuits, and fluid supp y and discharge pipes for the various-loading liquids which are provided with regulatin devices to allow of introducing or running o a plurality of loading liquids separately or to ether.

or this purpose both the fluid supply ipe and also the discharge pipe of the centri uge are provided with a multi-way cock in order to allow establishing a connection with any one of the supply or connecting vessels for the loading agent as desired.

The collecting vessels themselves are connected with liftlng mechanisms for example pumps or pulsometers which are in connection with the supply containers, so that the liquid used at any time for loading the goods circulates from the supply vessel into the cen- .25 trifuge, from there into the collecting vessel and back to the supply vessel.

The loading of textile materials containing silk has not hitherto been possible vin such a continuous apparatus, as numerous 3U washings, acidifications or neutralizations of the material treated have been necessary between the individual baths.

Y The application of the device according to the present invention has been rendered possible by the discovery that the objectionable Washings, acidiications or neutralizations between the separate baths can be eliminated,

so long as care is taken that the metallic salt,

' particularly stannic chloride, acts on the silk only in the presence of acid or acid salt.

These acid substances or mixtures themselves act on the silk containing textile material separately or along with the stannic chloride bath. Continuous, simple, and, from the economical point of view, profitable, loadin of the .material is rendered possible for the rst time by this process.

One form .of construction of the inventionrv is shown in the accompanying drawing in ".1 I

Figure 1 is a and Figure 2 is a side elevation of the same.

A dependent centrifuge 4 with base discharge is rovided below three vessels 1 2 55 and 3. The vessel 1 contains the acid, for example formic acid. The vessel 2 the metal :front elevation of the plant yloadingbath, for example the stannic chloride solution, and the vessel 3 the fixin solution, for example a mono-sodium dihydrpgen 00 phosphate solution.

A common pipe 5 is' connected to the three containers, the supply to which can be automaticallyv regulated by cocks 6a, v6, and 6b. The pipe 5 discharges its contents through a 05 pipe 7 intothe centrifuge 4. A discharge pipe 8 from the centrifuge 4 is provided with a three-way cock 9, which allows the liquid from the bath in use at any time to be led away through an of the separate pipes 10,

` 11, and 12 into col ecting vessels 13, 14 and 15.

The solutions pass from the collecting ves-v sels into separate pulsometers or pumps 16, 17, 18, which are connected respectively by pipes 19, 20 and 21 with the corresponding 75 supply vessels 1, 2 and 3.

The material is first introduced into the centrifuge 4 and acid is then added from the vessel 1 ,through the pipe 5, three-way cock 6, and inlet pipe 7. After a predetermined 8 time, during which the centrifuge is in operation, the acid is led through the pipe 8, three-way cock 9 and pipe 10 into the collecting vessel 13Land is returned by the latter through the pulsometer 16 and the pipe 19 85 to the supply vessel 1. The silk whlch has been well centrifuged is then treated with the stannic chloride solution in the same manner as with the acid and then, after it has again been well centrifuged, is treated with the mono-sodium dihydrogen'phosphate solution. Fourway cocks can also be used instead of three-way cocks if it is desired to employ, in addition, treatment with sodium silicate solution similarly as with the remaining loading agents.

The vessels, pipes 'and centrifuges used,\ are provided with acid resistant linings, for examplehard or vulcanized rubber.

The loaded material is removed from the centrifuge on completion of the loading )process and thoroughly washed in shallow vets or other Washing apparatus.

ll claim:

l. A method of loadin textile material consisting in treating. t e textile material successively with an acid, a metal loading solution and a fixingsolution consecutively in a single centrifuge Without removal of the material from said centrifuge during the consecutive steps of the process and without washing the material treated with the metal loading solution.

2. A method of lloedin textile material consisting of silk of enylind consisting in treatin the silk successively with un acid, e meta louding solution and 'e fixing solution consecutively in a single centrifuge Without removal of the material from said centrifuge during the consecutive steps ot' the process und without washing the silk l treated with the metel loading solution.
